Uber’s autonomous trucks, however, aren’t used to replace human drivers, according to a report by The New York Times. Rather, the trucks are operated with a licensed truck driver and equipped with an autonomous system that’s there to assist in navigating long highway hauls or to take over in case of emergency.

The self-driving trucks prove to be the latest development of Uber Freight, Uber’s free app that matches carriers with shippers. “We think self-driving technology has tremendous potential to solve some of the big problems that the trucking industry has today,” said product manager for Uber’s self-driving truck unit, Alden Woodrow. So far, Uber hasn’t disclosed many details regarding its self-driving trucks, like how many autonomous units are on the road, but it’s evident that companies (such as Tesla) are fighting to take the lead in advancing the truck industry.
